Step 2: Change the Air Filter

Start by changing your air filter. Simply take off the cover to the air-cleaner housing, remove the dirty filter and drop in a new one. Changing your filter every 12,000 miles is an easy way to keep your engine running smoothly. If you do most of your driving in dusty or sandy areas, you should change the air filter every 5,000 miles.

To ensure your fuel system is running at its peak, add a fuel cleaner to your tank every 3,000 miles. The cleaner removes deposits that can cause rough idle, engine hesitation and poor fuel economy.

Step 3: Check Recommended Octane Level

Check your vehicle's owner's manual for the recommended fuel octane level. Don't buy a premium grade if it's not required. It not only costs more but may actually reduce your fuel efficiency. Using gasoline with a lower than recommended octane level can cause misfiring and even over heating.

Step 4: Check Tires and Gas Cap

Even something as simple as properly inflating your tires, lightening your load or replacing a worn out gas cap can save your money. A gas cap with a faulty seal can cause fuel to evaporate from your tank, and under inflated tires consume about one mile per gallon of extra gasoline.

In addition to performing simple maintenance, changing your driving habits will also improve your vehicle's gas mileage. Avoid quick starts and sudden stops for starters. Combine errands whenever possible to reduce the number of short trips taken on a cold engine. SLOW DOWN! Gas mileage decreases rapidly at speeds above 60 miles per hour.
